modelica library to model fluid dynamic of HVAC systems

Changes from version 2.0.1

• Increase of performance by: -> diminution of iteration variable via a better management of explicit and implicit variables -> use of functions rather than equation on non linear and high order equations

• Compatibility with the new front end of the Open Modelica software (Version > 1.14)

• Management of transport and diffusion equations via Partial Derivative Equations rather than connection between multiple components

Changes in version 3.1

1-Minor corrections: - polynomialFlow: correction required to work with the version 1.16 of openModelica - gasConstant_X of the air Air_H2 media: correction in its declaration

2-Major corrections: - Correction in the called fonction to computed the derivative function of the saturation density of the MoistAir media (f4dc8833) - Correction in the calcualtion of the derivative function of the saturation density of the MoistAir media - Correction in the "UpwindFirstOrder" model when the flow was in reverse direction

3-Enhancements - FanVentilation: works with multi-species media - The saturation pressure fonctions have been changed to work with a MoistAir bellow the triple point condition. It does not mean that the media can model a condensable moist air bellow the triple point conditions - The orifices (except the compressible opening) can be initialised to a given velocity with a steady state condition. The flow regime can now be steady state or inertial.
